Beavers learn the reef knot and thumb knot and their uses as described in Colony programme plus pg 60
50cm of rope for each Beaver (rope is better than string for being able to see the knot)
Each lodge has a leader to demonstrate knot and explain uses. Beavers each try with the rope.
Notes - Different uses of knots: tying rope together, securing something to an object, stopping rope from passing through. Should note that reef knot is not a strong knot and should not be used for safety critical uses/loads. Knots used in many different activities, eg: sailing, mountaineering, fishing, around the home. Important features of knots: how easy they are to do up and undo, how reliable are they.
